ABNC SPECIMEN MONSTER LOT. Archival quality (after all, they did come from the American Bank Note Company archives) 1890s to 1950s period mini-collection of "SPECIMEN" overprinted and security punch-holed stamps, all neatly organized, identified and stored in a small high quality stockbook. This group was purchased back in the early 1990s by Kasimir Bileski at the famous ABNC Archives sales, who then sorted, researched and marketed the material. 828 stamps total, including regular, "Back of the Book" and fiscal issues. While there at first appears to be some duplication, the sets and singles have been identified for the different ABNC printing orders that they come from. The lot includes Bileski's extensive original detailed and informative sales blurbs noting that very few of some of the sets of these postal and fiscal issue Specimens and proofs exist. The Venezuela group was the most extensive offering of Latin American material that Bileski put together. Original 1994 Bileski retail price for this lot.
